Food supplement for ruminants - prepd. by heating animal offal contg. stomach and intestinal contents, mixing with easily fermentable carbohydrate and fermenting the mixt.

摘要

Feedstuff for ruminants is made by heating predigested food and slaughter offal contg. intestinal residues, mixing this with a material contg. easily fermentable carbohydrates, and fermenting the mixt. The process converts normally waste material into a valuable food prod. which is taken well by ruminants such as sheep and cows. Material contg. stomach and intestinal contents, which contains harmful bacteria and organisms such as Salmonellae and Coccidia, is converted into a biologically safe material due to the predominant fermentation by Lactobacilli, which predominate and suppress the other bacteria. In a pref. process, the animal offal material is heated and mixed with molasses as a cheap, easily fermentable material. Pref. the molasses is mixed in while the animal material is still hot. The amt. of fermentable material added must b sufficient to develop sufficient Lactobacilli to suppress the remaining bacteria. As fermentation proceeds, the pH falls gradually and after a few days remains constant. The prod. is obtd. as a slurry with a solids content of 4-20% which can be added to cattle feed.
